Doom

Intel Core i5-11400F and NVIDIA GeForce RTX 5080, tested with Doom, delivers strong frame rates across all tested resolutions and presets. The recorded data shows average FPS figures consistently well above the 60 FPS playable threshold, with the lowest average result appearing at 4K Ultra at 91.9 FPS. This combination of a 6-core, 12-thread Rocket Lake processor and a Blackwell 2.0 architecture GPU proves capable of handling the game's demands without dropping below playable levels at any setting.

Measured FPS Breakdown

The database contains measured average FPS values for this combination across three resolutions and four graphics presets. Minimum and maximum FPS values were not recorded, so the analysis relies entirely on average frame rates.

At 1920x1080, the results are uniformly high. Low settings produce an average of 311.6 FPS, Medium yields 299.6 FPS, High reaches 282.6 FPS, and Ultra still maintains 258.5 FPS. The spread from Low to Ultra is 53.1 FPS, which is relatively modest, indicating that even the most demanding preset leaves a substantial performance buffer.

Moving to 2560x1440, average FPS drops across all presets but remains very high. Low averages 272.4 FPS, Medium 240.2 FPS, High 201.5 FPS, and Ultra 162.8 FPS. The gap between Low and Ultra widens to 109.6 FPS, showing a stronger response to preset changes at this resolution compared to 1080p.

At 3840x2160, the performance scales down further. Low averages 147.9 FPS, Medium 129.1 FPS, High 107.9 FPS, and Ultra 91.9 FPS. The difference between Low and Ultra here is 56.0 FPS, which is smaller than at 1440p but still substantial. Every preset at 4K clears the 60 FPS threshold by a wide margin, with the lowest recorded average being 91.9 FPS at Ultra.

The pattern across resolutions shows that preset sensitivity increases from 1080p to 1440p but then moderates at 4K. This suggests that at 4K, the GPU is becoming the limiting factor, while at 1080p, the CPU may hold back the GPU in lower presets. The data indicates that the RTX 5080 is consistently capable of driving high frame rates in Doom, regardless of resolution or preset.

How This Combo Ranks

The combination of Intel Core i5-11400F and NVIDIA GeForce RTX 5080 ranks 313th out of 3712 tested combos in Doom, placing it in the top 8.4% of all tested hardware pairings for this game. This percentile position reflects the strong performance of the RTX 5080, which alone ranks in the 87th percentile against all GPUs in the database.

The CPU, by contrast, ranks in the 71st percentile against all CPUs, with an average benchmark score of 17177. The GPU has an average benchmark score of 56083, which is significantly higher than the CPU's score. This disparity indicates that the GPU is the dominant contributor to the combo's overall ranking.

When examining the nearest rivals for each component, the CPU sits within a narrow band of similar performers. The AMD EPYC 7H12 scores 17120, which is 0.3% lower than the i5-11400F's 17177. The Intel Core i5-12450H scores 17239, 0.4% higher. The AMD Ryzen 3 PRO 8300G scores 17278, 0.6% higher, and the Intel Core Ultra 7 164U scores 17074, 0.6% lower. These deltas are all within one percent, meaning any of these CPUs would produce nearly identical frame rates in Doom when paired with the same GPU.

For the GPU, the nearest rivals show slightly larger variations. The AMD Radeon 8060S scores 55757, 0.6% lower than the RTX 5080's 56083. The AMD Radeon RX 6750 GRE 12 GB scores 55698, 0.7% lower. The AMD Radeon Pro W5700X scores 54828, 2.3% lower, and the AMD Radeon RX 9070 GRE scores 57367, 2.2% higher. These differences suggest that swapping the RTX 5080 for any of these GPUs would change performance by only a few percent, which is unlikely to alter the playability verdict.

Best Settings per Resolution

At each resolution, the most demanding preset that still maintains an average of at least 60 FPS is Ultra. The database confirms that all four presets, Low, Medium, High, and Ultra, achieve playable frame rates at every resolution tested.

At 1920x1080, Ultra is the best setting, yielding an average of 258.5 FPS. This is nearly four times the playable threshold, so there is no incentive to lower settings for performance reasons. Even at Ultra, the frame rate is high enough for fast-paced FPS gameplay.

At 2560x1440, Ultra remains the best setting, with an average of 162.8 FPS. This is still far above 60 FPS, leaving ample headroom. The gap between Ultra and the next lower preset, High at 201.5 FPS, is 38.7 FPS, but both are comfortably playable.

At 3840x2160, Ultra averages 91.9 FPS, which is the lowest result in the entire dataset. Despite this, it clears the 60 FPS threshold by 31.9 FPS, so the combination can run the game at maximum settings at 4K without issue. The verdict data confirms that Ultra is the best setting at all three resolutions, with average FPS of 258.5, 162.8, and 91.9 for 1080p, 1440p, and 4K respectively.

Similar Performance Alternatives

Based on the nearest rivals for the CPU and GPU, several alternative combinations would behave similarly in Doom. The CPU comparisons show that the i5-11400F is statistically tied with the AMD EPYC 7H12, Intel Core i5-12450H, AMD Ryzen 3 PRO 8300G, and Intel Core Ultra 7 164U. All of these processors have average benchmark scores within 0.6% of the i5-11400F, so swapping any of them in would not meaningfully change frame rates.

For the GPU, the AMD Radeon 8060S and AMD Radeon RX 6750 GRE 12 GB are the closest matches, with scores 0.6% and 0.7% lower respectively. The AMD Radeon Pro W5700X is 2.3% slower, while the AMD Radeon RX 9070 GRE is 2.2% faster. In practical terms, any of these GPUs paired with the i5-11400F would produce frame rates within a few percent of the measured values, meaning all tested resolutions and presets would remain playable.

A combination using the AMD Radeon RX 9070 GRE might see slightly higher average FPS, perhaps 2% more, while the AMD Radeon Pro W5700X would be slightly slower. However, since the lowest measured average is 91.9 FPS at 4K Ultra, even a 2.3% reduction would leave the frame rate above 89 FPS, still far above the playable threshold. The data indicates that the performance envelope around this combo is narrow, and all nearby alternatives would deliver similar experiences in Doom.

CPU and GPU Roles

The scaling between resolutions reveals which component limits performance in Doom. At 1920x1080, the average FPS across all presets is very high, ranging from 258.5 to 311.6. The difference between Low and Ultra at 1080p is only 53.1 FPS, which is relatively small in absolute terms. This suggests that at 1080p, the CPU may be constraining the GPU, particularly at lower presets where the GPU has spare capacity.

At 2560x1440, the average FPS drops more sharply with preset changes. The gap between Low and Ultra grows to 109.6 FPS, indicating that the GPU is becoming more influential. The CPU can still feed the GPU adequately, but the GPU's workload scales more noticeably with settings at this resolution.

At 3840x2160, the average FPS continues to drop, but the gap between Low and Ultra narrows to 56.0 FPS. This pattern suggests that at 4K, the GPU is the primary bottleneck, and the CPU's role diminishes. The i5-11400F, with its 6 cores and 12 threads, provides enough processing power to keep up with the RTX 5080 at 4K, but the GPU's rendering workload dominates the frame rate.

Comparing resolution scaling at the same preset, moving from 1080p to 1440p reduces average FPS by roughly 30% to 40% depending on the preset. Moving from 1440p to 4K reduces average FPS by a similar margin. This consistent scaling indicates that the GPU is the main driver of performance differences across resolutions, while the CPU maintains a stable foundation.

The CPU's benchmark data supports this interpretation. The i5-11400F scores 14340 in Cinebench R23 multicore and 2024 in single-core, placing it in the 71st percentile. These scores are sufficient for high-refresh-rate gaming, but they are not exceptional. In Doom, a game that relies heavily on GPU throughput, the CPU's role is to maintain a minimum frame rate floor rather than to push maximum FPS.

The Verdict

This PC can run Doom at all tested resolutions and presets with average FPS well above 60. The database's verdict confirms that at 3840x2160, all four presets (Low, Medium, High, Ultra) are playable, with the best settings being Ultra at 91.9 FPS. At 2560x1440, all presets are also playable, with Ultra at 162.8 FPS. At 1920x1080, all presets are playable, with Ultra at 258.5 FPS.

The lowest performance point in the entire dataset is 4K Ultra at 91.9 FPS, which still exceeds the 60 FPS playable threshold by 31.9 FPS. There is no scenario in the recorded data where this combination falls below 60 FPS. The RTX 5080's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth provide ample resources for Doom's textures and effects at 4K, while the i5-11400F's 12 threads handle the game's logic without bottlenecking.

For players targeting high refresh rates, the 1080p results are particularly strong, with even Ultra averaging 258.5 FPS, which supports 240 Hz monitors. At 1440p, Ultra at 162.8 FPS also supports high-refresh displays. At 4K, the frame rate drops below 100 FPS but remains above 90 FPS, which is suitable for 60 Hz or 90 Hz displays. The data shows this combo is fully capable of running Doom at maximum settings across all standard resolutions.
